Responsive farming for soil type at Wharminda locations

At Wharminda the focus is on managing risk through variable rate technology (VRT) using different inputs over variable soil

Key messages
  • In an above average season a high input system was the “best bet”.
  • Variable rate had reduced production but at a lower risk.
